Abstract: PURPOSE: To enable to effect a synthetic temperature control by a compressor, an indoor fan and the like by a method wherein a dfferential amplifier connecting with a temperature regulator at one side of the input terminal thereof and with a temperature sensor circuit at the other side of the input terminal thereof is provided and the output thereof is controlled.  
     CONSTITUTION: The differential amplifier 13 connecting with the temperature regulator 2 at one side of the input terminal thereof and with the temperature sensor circuit 1 by a thermistor at the other side of the input terminal thereof is provided and the circuit is constituted so as to be able to control the compressor 5 and the fan motor 7 by only the output thereof. Upon room heating, when the room heating is begun from a temperature lower than T 31 , for example, the compressor 5 is operated and the motor 7 is rotated at a high-speed rotation RH since the output voltage thereof is lower than V 1 . Subsequently, when the temperature is risen and the output voltage V 1  (room temperature T 31 ') is attained, the speed of the motor 7 is brought into a stepless speed change area proportional to the value of the room temperature and the number of revolution thereof is decreased as the temperature is risen. Thereafter, when the output voltage V 2  (room temperature T 32 ') is attained, the number of revolution of the motor becomes RL and it is restricted at RL even when the room temperature is risen to the temperature higher than T 32 '.

IPC: H01J37/21
Filed: 1987-01-12
Abstract: PURPOSE:To reliably focus a beam spot in a short time by measuring the beam current value of the ion beam passing the opening of a beam mask in relation to the beam spot center position of the ion beam when the beam is scanned and emitted in two directions respectively. CONSTITUTION:An ion beam 2 is scanned and emitted toward a beam mask 1 so as to over-scan to both outsides of the opening 1a of the beam mask 1 in the vertical direction V and the horizontal direction H through the opening center F of the beam mask 1. The beam current value of the ion beam 2 passing the opening 1a of the beam mask 1 is measured in relation to the beam spot center position of the ion beam 2 when the beam is scanned and emitted in the vertical direction V and the horizontal direction H respectively. The measured beam current value is plotted in relation to the beam spot center position. Thereby, a trapezoidal wave-form is formed for the vertical direction V and the horizontal direction H respectively. Then, it is differentiated to form a differential wave-form, and the ratio PH/PW between its height PH and width PW, thus focusing can be simply performed.

Projections 185 as long as a nearly half of a length of the boss 201 are axially formed on the external periphery of the shaft 18. To combine the shaft and the plate, the shaft 18 is squeezed into the boss 201 in the direction of an arrow shown in the drawing and then one 27 of pressing fittings 26, 27 disposed on the both sides of the swash plate 20 is pressed left. A ringlike projection 27a of the pressing fittings 27 causes plastic flow at a partial area on the boss 201 to fill the groove 181 in the shaft 18, by which a great connection force against vibration or an impact can be obtained.

Filed: 1993-01-18
Abstract: PURPOSE:To provide a seal adjusting mechanism for spindle which can certainly seal between a spindle and a housing for it even under high speed rotating, and can hinder the heat emission phenomenon of a sealing member. CONSTITUTION:A flange member 26 and a weight member 28 are furnished on a spindle 10, and a sealing member 30 is installed on a spindle housing 12. When the spindle 10 is rotating in a low speed, the weight member 28 is positioned inside in diametric direction of the spindle 10, and the flange member 26 is pushed to the right by a spring member 24 to be put in slide contact with the sealing member 30.
